372. 指纹矩阵在复杂介质中目标检测与表征

from 知为谁 · host 知为谁

这两篇资料概述了一种名为“指纹矩阵”的创新成像技术,该技术旨在解决复杂多重散射介质中的目标检测和定位难题。传统成像方法在诸如浓雾、沙土或生物组织等强散射环境中会失效,但该方法通过比较目标在无干扰环境中的散射“指纹”矩阵(一个数学模型)与在散射介质中测得的反射矩阵,利用两者之间的相关性来确定目标的位置和特征。研究团队通过超声波实验验证了该方法的普适性,成功在强散射颗粒悬浮液中定位了金属球,并在医学成像中检测了乳腺病灶标记物,甚至可用于定量成像以分析肌肉纤维结构。该技术不仅能显著提高对比度和定位精度,且其计算量与标准共焦成像相当,展示了在雷达、声纳和医学等多个领域应用的潜力。内容来源:https://arxiv.org/html/2502.07052v2https://phys.org/news/2025-10-treasures-physics-fingerprint-matrix-method.html
